cam = espcamera.Camera(
    data_pins=[board.CAM_D0, board.CAM_D1, board.CAM_D2, board.CAM_D3,
               board.CAM_D4, board.CAM_D5, board.CAM_D6, board.CAM_D7],
    external_clock_pin=board.CAM_XCLK,
    pixel_clock_pin=board.CAM_PCLK,
    vsync_pin=board.CAM_VSYNC,
    href_pin=board.CAM_HREF,
    pixel_format=espcamera.PixelFormat.RGB565,
    frame_size=espcamera.FrameSize.QVGA,
    i2c=i2c,
    external_clock_frequency=20_000_000,
    framebuffer_count=2
)

while True:
    frame = cam.take(1)
    display_bus.send(0x36, b'\x70')
    display_bus.send(0x2A, struct.pack(">HH", 0, 319))
    display_bus.send(0x2B, struct.pack(">HH", 0, 239))
    display_bus.send(44, frame)
    
    if not button.value:
        print("framebuffer_count without reconfigure:", cam.framebuffer_count)
        cam.reconfigure(
            pixel_format=espcamera.PixelFormat.JPEG,
            frame_size=espcamera.FrameSize.QVGA,
            framebuffer_count=2
        )
        time.sleep(0.1)

        jpeg = cam.take(1)

        cam.reconfigure(
            pixel_format=espcamera.PixelFormat.RGB565,
            frame_size=espcamera.FrameSize.QVGA,
            framebuffer_count=2
        )
        time.sleep(0.1)

        print("framebuffer_count after reconfigure:", cam.framebuffer_count)

Behavior

framebuffer_count is set to 2 before reconfigure() is called, afterwards it is set to 1 despite explicitly setting to 2.
